Hi Felix,
----- Original Message -----
Hey Guys,
I've been using Fedora on Raspberry Pis for a while now and I love it. The
only problem I consistently face is the process of reinstalling (due to
broken SD, sudo SNAFU etc.):
1. Put SD card in secondary machine
2. DD the Fedora aarch64 image onto SD card
3. Grow partition
4. Put SD card back
5. Boot
6. Go through initial setup
7. Update all packages
8. Continue with regular config and host management
Since I've used PXE in x86_64 environments for years, I started looking into
doing the same for the RPI. The idea is to condense the process into a
single step:
1. Either insert (new) empty SD card or destroy the partition table on the
active SD card and reboot
In theory this should work because by default the RPI 3 B+ boots from SD card
first and on failure moves on to PXE which then loads the PXE components
from TFTP and starts the kickstart process. That should give (with the
proper kickstart instructions) a completely headless and unattended
installation environment for RPI.
This has been done for preseeding raspbian here:
https://github.com/debian-pi/raspbian-ua-netinst and I'd love to do this for
Fedora as well.
I brought up my PXE environment and the RPI is reliably pulling everything
from initial bootcode.bin all the way to U-Boot and I end up with a U-Boot
shell prompt.
Then loading grubaa64.efi through TFTP brings me to the GRUB shell which
pulls the vmlinuz and initrd.img devices and starts the kernel.
This is where I'm stuck. When the system is loading the stage2 install.img it
looks like it's running out of space on the tmpfs and I'm getting a "No
space left on device" error and kernel panic (not sure yet if they are
related).
I'm not very skilled in dissecting initrd images so I'd appreciate any
pointers. Is there a kernel or anaconda parameter to increase the tmpfs
size? Maybe the 1G of memory is just not big enough to hold the ~470MB
install.img AND have enough left to finish the kickstart. Would it be
feasible to reduce install.img?
A network installs need about 2G ram unfortunately. You can use NFS to
provide the initramfs using 'inst.stage2=nfs://192.168.X.X:/path/to/install.img'.
